Ina Lohr (1903–1983) was a pioneer of the Early Music movement, whose influence has largely gone unnoticed to date. Coming from the Netherlands, she first became the assistant of the Basel patron of the arts, Paul Sacher (1906–1999), before participating in the founding of the Schola Cantorum Basiliensis, the new “Institute for Teaching and Research”. Through her own focus on Gregorian chant and Protestant sacred music, in addition to Hausmusik (‘house music’) and theoretical subjects, she determined to a great extent the content and the ideological slant of the course of study. By means of archival research in Switzerland and the Netherlands, supplemented by interviews with her former students, the contures of her pedagogical and aesthetic ideals were investigated. Further, the sources of the ‘Swiss-Dutch axis’ in the Early Music movement were analyzed, the cultural context of the Singbewegung (Singing Movement), both within and without Germany examined, thus fleshing out the biography of this influential outsider.
